To date, there are a number of interesting numbers that reflect the structure and functioning of the brain. So, according to rough estimates, it contains about 100 billion neurons – cells that process, organize and remember information. If you add up all the nerve fibers that are inside both hemispheres, they will stretch in a line half a million kilometers long. The surface of the brain is not smooth, it has a network of convolutions, which eventually form an area of about 20 m2.
No less impressive is the work of the brain. The impulses from cell to cell and to organs are transmitted at a speed of 288 km / h, but with age the speed slows down slightly, by about 10-15%. Therefore, older people are slower, think longer, remember worse. If we compare the brain with a computer, its memory capacity reaches 5 Petabytes. To understand a volume of this kind are 300 years of continuous film viewing. But it’s not just the brain’s amazing capabilities, it’s such an amazing and unique organ that neuroscientists are constantly learning something new.
